Abstract
Embodiments of the present invention relate to a method for managing user information in a SIP network and a corresponding device. The method comprises the following steps: after the SIP access gateway is restarted, a restart timer is started; and in the valid period of the restart timer, responding to a heartbeat message from a network element, and sending a heartbeat reply message to the network element, wherein the reply message comprises the restart time of the SIP access gateway. And if the difference between the restarting time and the current time of the SIP access gateway is less than the interval time of the heartbeat message, the network element sends a registration request to the SIP access gateway, wherein the registration request contains the user information of all the users represented by the network element. An apparatus capable of implementing the above method is also disclosed.
Description
Technical Field
Embodiments of the present invention relate generally to communication technology and, more particularly, relate to an apparatus for managing user information.
Background
In some remote or sparsely populated locations, such as: some small villages, some islands, etc. generally only deploy SIP Access gateways (Access gateways), these SIP Access gateways communicate with SIP application servers deployed in towns or continents, and these SIP application servers provide voice services or most value-added services for users in the jurisdiction of the SIP Access gateways. However, once the communication between the SIP access gateway and the SIP application server is interrupted, for example, the optical fiber line is interrupted due to earthquake, the users in the SIP access gateway domain cannot communicate with each other, that is, the "local" communication under the SIP access gateway is also interrupted.
Many telecommunications customers desire: in case of communication interruption between the SIP access gateway and the SIP application server, the inside of the isolated place can communicate with each other. Accordingly, an enhanced SIP access gateway has emerged that is capable of providing basic one-to-one call services, with substantially stateless forwarding of SIP messages, i.e., without recording the state of the call. The enhanced SIP access gateway can provide basic telephone call services for terminal users, user agents and other non-enhanced access gateways in a local network by utilizing the simple call application processing function of the enhanced SIP access gateway, and the enhanced SIP access gateway is popularized by a plurality of clients and is deployed in an increasing number.
Since the enhanced SIP access gateway has low requirements on services and is deployed at a high ratio, customers want the enhanced SIP access gateway to be simple and low-cost to implement. Therefore, the enhanced SIP access gateway does not pre-configure the user information, and only obtains and saves the user information through registration learning, i.e. through user registration. However, after the SIP access gateway is restarted for some reasons, all the user information on the SIP access gateway is lost, because the restart is completed in a short time, and the time length of the timer triggering the user to re-register is longer (usually 1800 seconds to 3600 seconds), therefore, many users cannot receive calls due to the loss of the user information before the SIP access gateway is restarted to complete the re-registration of all the users, and users in the domain of the SIP access gateway cannot normally communicate.
Therefore, there is a need to provide a method to solve the problem of communication failure due to restart of such an enhanced SIP access gateway.

Detailed Description
Embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. While certain embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be embodied in various forms and should not be construed as limited to the embodiments set forth herein, but rather are provided for a more thorough and complete understanding of the present invention. It should be understood that the drawings and the embodiments of the present invention are illustrative only and are not intended to limit the scope of the present invention.
The terms "include" and variations thereof as used herein are inclusive and open-ended, i.e., "including but not limited to. The term "based on" is "based, at least in part, on". The term "one embodiment" means "at least one embodiment"; the term "another embodiment" means "at least one additional embodiment". Relevant definitions for other terms will be given in the following description.
The present invention is described in further detail below with reference to the attached drawing figures.
FIG. 1 illustrates an example network architecture in which embodiments according to the invention may be implemented. In this embodiment, SIP access gateway 101 is connected to SIP server 102. User agents UA103, UA104, end user UE105 and SIP access gateway 106 access the network through SIP access gateway 101.
As described above, when the connection between SIP access gateway 101 and SIP server 102 is disconnected, in order to ensure that a "local" call can be performed between users in the domain of SIP access gateway 101, SIP access gateway 101 can provide a basic call service, and SIP messages are forwarded substantially without state, that is, the state of the call is not recorded. SIP access gateway 101 may utilize its own simple call application processing functions to provide basic telephone call services for user agent UA103, user agent UA104, end user UE105, and other non-enhanced SIP access gateways 106 within the local network. The SIP access gateway 101 does not configure the user information in advance, and obtains and saves the user information only through registration learning, that is, through user registration.
It should be understood that the type and number of devices and/or elements shown in fig. 1 are for illustrative purposes only and are not intended to be limiting. The network architecture may also typically include devices such as gateways, which are not shown in fig. 1 for simplicity.
Fig. 2 shows a schematic diagram of a SIP access gateway restart in the prior art. This process is described in detail below in conjunction with fig. 1. In this embodiment, the communication between SIP access gateway 101 and SIP server 102 is interrupted.
First, the user agent UA103 sends (S201) a registration message, such as a REGISTER message, containing user information of the user represented by the user agent UA103, to the SIP access gateway 101. When the user agent UA103 represents multiple users, the user agent UA103 may send multiple registration messages to the SIP access gateway 101.
After receiving the registration message, SIP ap 101 stores the user information. Subsequently, the 200OK is sent (S202) to the user agent UA 103. After receiving the 200OK reply message, the UA103 starts (S203) a registration timer.
Then, at some point, SIP access gateway 101 restarts for some reason (S204). After the SIP access gateway 101 is restarted, all the user information stored thereon will be lost. At this point, many users will not be able to receive calls due to the lack of user information.
When the registration timer of the user agent UA103 times out (S205), the user agent UA103 REGISTERs with the SIP access gateway 101 again, that is, the user agent UA103 sends (S206) one or more registration messages, such as REGISTER messages, to the SIP access gateway 101, where the registration messages include user information of the user represented by the user agent UA 103. After receiving the user information, SIP access gateway 101 stores the user information. When all the user agents in the domain of the SIP access gateway 101 finish the re-registration, the user information on the SIP access gateway 101 is completely recovered, and the user in the domain of the SIP access gateway 101 can recover the local communication.
It can be seen that, in the prior art, after communication between SIP access gateway 101 and SIP server 102 is interrupted, if SIP access gateway 101 is restarted, many users in the jurisdiction of SIP access gateway 101 cannot receive calls due to the loss of user information from the restart of SIP access gateway 101 to the completion of user agent re-registration. This is the problem to be solved by the present invention.
Fig. 3 shows a schematic diagram of a process for managing user information according to an embodiment of the invention. This process is described in detail below in conjunction with fig. 1.
In a SIP network, a network element connected to a SIP access gateway periodically sends a heartbeat (heartbeat) message to the SIP access gateway for monitoring whether communication between a user agent and the SIP access gateway is normal. As shown in fig. 3, the user agent UA103 sends (S301) a heartbeat message, which may be a REGISTER message or an OPTIONS message, to the SIP access gateway 101. Upon receiving the message, SIP access gateway 101 sends (S302) a reply message 200OK to user agent UA 103.
The user agent UA103 sends (S303) a registration message, such as a REGISTER message, containing user information of the user represented by the user agent UA103, to the SIP access gateway 101. When the user agent UA103 represents multiple users, the user agent UA103 may send multiple registration messages to the SIP access gateway 101. After receiving the message, the SIP access gateway 101 stores the user information, and then sends a 200OK to the user agent UA 103. After receiving the 200OK, the UA103 starts (S305) a registration timer.
When the time interval of the heartbeat message is reached, the user agent UA103 may again send (S306) the heartbeat message, which may be a REGISTER message or an OPTIONS message, to the SIP access gateway 101. Upon receiving the message, the SIP access gateway 101 sends (S307) a reply message 200OK to the user agent UA 103.
After the SIP access gateway 101 restarts, when the time interval of the heartbeat message reaches again, the UA103 sends (S309) a heartbeat message, which may be a REGISTER message or an OPTIONS message, to the SIP access gateway 101 again. After receiving the message, the SIP access gateway 101 sends (S310) a reply message 200OK to the user agent UA103, where the reply message includes a restart time of the SIP access gateway 101, where the restart time may be a relative time or an absolute time, for example: the restart time is 10 minutes before and 22: 05, and the like.
It will be appreciated by those skilled in the art that the time at which SIP access gateway 101 is restarted may be included in the heartbeat reply message described above in any suitable manner, for example, in the WARNING header of a SIP message.
After receiving (S310) the heartbeat reply message, the UA103 of the user agent reads the restart time of the SIP access gateway 101 included in the heartbeat reply message, and determines (S311) whether a difference between the restart time and the current time is smaller than a time interval of the heartbeat message.
If the difference between the restart time and the current time is smaller than the time interval of the heartbeat message, which indicates that the user information of the user agent UA103 on the SIP access gateway 101 is lost, the user agent UA103 may re-register. The user agent UA103 re-sends (S312) to the SIP access gateway 101 one or more registration messages, such as REGISTER messages, containing user information of the user represented by the user agent UA 103. After receiving the message, SIP access gateway 101 stores the user information, and then sends a 200OK to user agent UA 103. In some embodiments, SIP access gateway 101 may not be able to determine whether the registration message is for registration or for heartbeat detection, and SIP access gateway 101 may still include the time at which SIP access gateway 101 restarted in the 200OK message.
When the restart timer on the SIP access gateway 101 times out (S314), the SIP access gateway 101 considers that it has obtained the user information of the user agent UA 103. Therefore, after receiving (S315) the heartbeat message of the user agent UA103 again, the user agent UA103 is not required to register again. Upon receiving (S315) the heartbeat message, SIP access gateway 101 sends (S316) a reply message 200OK to user agent UA103, which no longer contains the time at which SIP access gateway 101 restarted.
It can be seen that, in the present invention, after the SIP access gateway 101 is restarted, the replies of all heartbeat messages received by the SIP access gateway include the restart time of the SIP access gateway, and after receiving the replies, the user agent, the terminal user or other SIP access gateways re-register according to the judgment result. The time interval of the heartbeat message is usually short, such as 60-90 seconds. By adopting the method, after the SIP access gateway 101 is restarted, the user information of all users in the jurisdiction of the SIP access gateway can be obtained again in a short time, and the time for losing the voice service is greatly shortened.
Fig. 4 shows a block diagram of an apparatus for managing user information according to an embodiment of the present invention. It is to be appreciated that apparatus 400 may be implemented at a SIP access gateway, such as SIP access gateway 101. The apparatus 400 comprises: a timer starting means 401 and a first sending means 402.
The operation of the apparatus 400 is described in detail below with reference to fig. 1 and 3.
For some reason SIP access gateway 101 restarts and at the same time timer starting means 401 starts the restart timer.
After the SIP access gateway 101 is restarted, after the SIP access gateway 101 receives a heartbeat message (such as a REGISTER message or an OPTIONS message) of some network elements, the first sending device 402 sends a heartbeat reply message to the network element, where the reply message includes a restart time of the SIP access gateway 101, and the restart time may be a relative time or an absolute time, such as: the restart time is 10 minutes before and 22: 05, and the like. The network element may be a user agent UA103 or a user agent UA104 or an end user UE105 or other non-enhanced SIP access gateway 106.
It will be appreciated by those skilled in the art that the time at which SIP access gateway 101 is restarted may be included in the heartbeat reply message described above in any suitable manner, for example, in the WARNING header of a SIP message.
Subsequently, after receiving one or more registration messages for re-registering the network element, the SIP access gateway 101 stores the user information of the user represented by the network element.
When the restart timer on SIP access gateway 101 times out, SIP access gateway 101 considers that it has obtained the user information of all users represented by the network element. Therefore, after receiving the heartbeat message of the network element again, the network element directly sends a heartbeat reply message to the network element without registering again, wherein the heartbeat reply message does not contain the time for restarting the SIP access gateway 101 any more.
Fig. 5 shows a block diagram of an apparatus for managing user information according to an embodiment of the present invention. It is understood that the apparatus 500 may be implemented at a user agent (e.g., user agent UA103 or user agent UA104) or an end user (end user UE105) or a SIP access gateway (other non-enhanced SIP access gateway 106). The apparatus 500 comprises: a receiving means 501 and a second transmitting means 502.
The operation of the apparatus 500 is described in detail below with reference to fig. 1 and 3.
First, receiving device 501 in user agent UA103 receives a heartbeat reply message, such as 200OK, from SIP access gateway, including the time at which SIP access gateway 101 restarts.
Subsequently, the UA103 determines whether the difference between the restart time and the current time is smaller than the time interval of the heartbeat message. The heartbeat message may be a REGISTER message or an OPTIONS message. If the difference between the restart time and the current time is smaller than the time interval of the heartbeat message, which indicates that the user information of the user agent UA103 on the SIP access gateway 101 is lost, the user agent UA103 will re-register on behalf of all users thereon. The second sending means 502 resends (S312) the registration message, such as a REGISTER message, containing the user information of the user represented by the user agent UA103 to the SIP access gateway 101. When the user agent UA103 represents a plurality of users, the second sending means 502 sends a plurality of registration messages to the SIP access gateway 101.
